A. Purpose
The purpose of this manual is to present a guide for proper
installation, maintenance, and operation of the Direct Gas-
Fired System, and supplement, but not to replace, the
services of qualified field service personnel to supervise the
initial start-up and adjustment of the unit. Persons without
previous experience with commercial and industrial heating
equipment should not attempt the initial adjustment and
checkout procedure which is essential before such
installations may be considered ready for operation. This
manual should be made readily available to all operating
personnel as an aid in troubleshooting and proper
maintenance.
B. Shipping
Direct Gas-Fired units are shipped completely assembled
where shipping limitations allow. Optional inlet hoods
or other large accessories are assembled and shipped
mounted and wired whenever possible within limitations of
shipping and handling. Any optional accessories shipped
separately are shipped as assembled sections.
Shipments are made F.O.B. Dallas,Texas by flatbed truck
or LTL shipment. The unit is securely strapped, tied, and
blocked to prevent shipping damage. All shipments are
checked by an inspector before they are accepted by the
carrier. Parts that are shipped unmounted are noted
on the bill of lading. These parts, where feasible, are
packaged and shipped with the units. Upon receipt of
shipment, all units should be checked against the bill of
lading to insure all items have been received. All equipment
(and any optional accessories) should be checked carefully
for physical damage in the presence of the carrier’s
representative. If parts are missing or damage has occurred,
a claim should be filed immediately with the carrier.
All Direct Gas-Fired units are given a minimum 140 point
operations test and control circuit checkout before ship-
ment. Copies of the wiring diagram, piping diagram and bill
of material are included with each unit shipped.
If correspondence with the factory is necessary, please
provide the unit model and serial number.
C. Optional Factory Service
Periodic service on any piece of mechanical equipment
is necessary for efficient operation. A nationwide service
support network is available to provide quick and dependable
servicing of make-up air, heating, ventilating, or air handling
types of equipment. The factory also offers start-up service
which includes the presence of a service engineer to
supervise the initial start-up and adjustment of the equipment
and provide instructions for the owner’s maintenance
personnel on proper operations and maintenance. Consult
factory for quotations on periodic or start-up service.
